JOHN M. MATTIS, OF TRIPP, SOUTH DAKOTA.

COW'-MILKER.

Specification of Letters Patent.

Patented Feb. 4, 1908.

Application filed February 25,1907. Serial No. 359.141.

To all whom it may concern:

Be it known that 1, JOHN M. MA'TTIs, a citizen of the United States, residin at Tripp, in the county of Hutchinson and State of South Dakota, have invented a new and usekept clean.

Another object of m invention is to provide a device which wil manipulate the teats without in'uring the same, thereby overcoming the dif culties no'w existing with'devices of this character now in use.

With these and other objects in View, the invention consists in the novel features of construction, combination and arran ement of parts hereinafter fully described and pointed out in the claims.

In the drawing forming a part of this specification:-F igure 1 is a perspective view of my improved milking device. Fig. 2 is a top plan view of the same. Fig. 3 is a perspective view of the base showing the operating mechanism detached.

In the drawing A indicates a base formed preferably of wood ro-vided with a central upwardly projecting lock A having inclined sides. A sheet of anysuitable metal B is secured over the block, the ends of which are bentu wardly forming troughs'B adapted to catch the milk. A spout B is formed on one end of one of the troughs B, under which is arranged an inclined trough C which extends up under the other trough B on the opposite side of the block adapted to convey the milk to a pail D, arranged under the lower end of the trough Mounted on pins secured in the edges of the base to each side of the center, are oppositely disposed upwardly extending outwardly bowed arms E, and 1 provided with :perturcd ends, in which are mounted shafts It, 1 having grooved pulleys E F secured on the outwardly extending ends for the purpose hereinafter described.

Secured on the shafts E, and F by nuts 5 adjacent the arms E and F are bars G and H provided with apertured ends in which are mounted the stud-pins I, J of spaced rollers I and J, which are preferably formed of rub.- ber. The arms E and F are provided with eyes E F adjacent. their upper ends, in which are secured the ends of coil-springs K, L carried by eye-bolts K, and L, mounted in brackets K L secured to the block A, on which are mounted thumb-nuts K L? so that the tension of the spring can be adjusted when d esircd. These springs draw the arms, towards the inclined block so that the teats will be squeezed between the same when the q .bars carrying the rollers are rotated, so as to bring the roller into engagement with the teats as will be hereinafter fully described;

A bracket M is secured centrally to the edge of the base and end of the block, provided with upwardly extending a ertured lugs M, in which is mounted a shaft carrying a crank-arm N provided with a double.

grooved pulley O carrying belts P and Q which pass over the pulleys E, F the belt Q springs. Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. in a device of the kind described, the cmnbination with a base provided with a block having inclined sides, of a sheet of metal secured over said blocks provided with as the rollers pass down over the teats whichare held into contact with the same, by the.

being twisted so as to make the bars H rotate The base is troughs at its ends, spring actuated arms mounted on said base and rollers carried by said arm.

2. The combination with a base provided with an upwardly extending block having converging sides, of spring actuated arms mounted on said base carrying a shaft, arms mounted on said shaft carrying rollers adapted to engage said sides of said blocks and means for operating said shaft.

The combination with a base provided with an upwardly extending block, of a sheet of metal secured over said block provided with troughs at its ends, spring actuated arms mounted on said base carrying shafts, bars secured on said slial'ts, rollers mounted in said bars and means for operating said 1 shalt.

combination with a base provided with a block having converging sides, of arms carried by said base, a shalt mounted in said arms, bars mounted on said shalt carrying rollers adapted to engage the sides of said block and means for operati said shaft.

5. The eon'ibination with a base provided With an upwardly extending block having inclined sides, of a sl.;-et o'l metal secured over said block provided with troughs at its ends, a trough arranged under the lower ends of said trough, arms carried. by said base and rollers carried by said arms.

p 6. The combination with a base provided with an upwardly extending block, of troughs arranged on said base to each side of the block, spring, actuated arms mounted on said A base, shafts mounted in said arms provided 4. in a device oi the kind described, the

with pulleys, bars secured on said shafts, rollers mounted in said bars, a bracket secured to one end of said block, a shaft mounted in said bracket, a crank-shalt secured over said shalt provided with a grooved pulley and belts carried by said pulleys passing over the pulleys, carried by the shafts.
